Biological monitoring of genotoxicity to organophosphate pesticide exposure among rice farmers: Exposure-effect continuum study
Background: This study has used biomarker of exposure-effect continuum to examine the biological characteristics of organophosphate (OP) toxicity and its genotoxic effect among rice farmers. Materials and Methods: A cross-sectional study was conducted among 160 pesticide exposed rice farmers and 160 adults from the fishing village as the unexposed group. They share the common socio-economical ...
متن کاملBIOLOGICAL MONITORING OF MERCURY EXPOSURE IN DENTISTS OF TEHRAN
In order to assess the risk for mercury poisoning in dentists, urine specimens were collected and analysed from 250 dentists (190 male, 60 female). Subject data and pertinent health symptoms were asked via a questionnaire. The results indicate that the mean and standard deviation of mercury values were 51.3± 38.0 µg/L, while 27.2 percent of dentists had levels within normal limits (0-19 µg/...
متن کاملPersonnel internal radiation exposure to iodine-125 in a radioiodination laboratory: Exposure levels and trends
ABSTRACT Background: Monitoring internal exposure of individuals handling significant amounts of iodine-125 (I-125) for iodination is of great importance. These individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to I-125. Considering radiological toxicity of this radionuclide its monitoring in the w...
متن کاملFuture directions in the use of DNA adducts as internal dosimeters for monitoring human exposure to environmental mutagens and carcinogens.
Scientific opportunities generally arise when two or more research areas converge and/or advances in methodology occur. This occurred at the turn of the 19th century in the field of infectious bacterial and fungal diseases. As we draw near to the 21st century, research in the laboratory is providing us with both critical information on mechanisms of carcinogenesis and new technological advancem...
متن کاملBrain circuits for the internal monitoring of movements.
Each movement we make activates our own sensory receptors, thus causing a problem for the brain: the spurious, movement-related sensations must be discriminated from the sensory inputs that really matter, those representing our environment. Here we consider circuits for solving this problem in the primate brain. Such circuits convey a copy of each motor command, known as a corollary discharge (...
